Abstract RU 2071887 C1

FIELD: welding; machine for production and household application; charging of storage batteries, engine starting. SUBSTANCE: device has transformer with divided primary and secondary windings. Making of secondary winding in form of cylindrical and disc windings and selection of definite relationship between winding turns and also selection of parameters of capacitor installed at transformer input makes it possible to control no-load voltage and short-circuit current. Use of oscillator provides stability of arc burning. EFFECT: enlarged operating capabilities. 3 dwg
